I think that electrons have a specific mass and charge.  Same for 
protons.  Basic question.  Have the mass and charge of the electron
and proton been clearly and coherently derived from the photoelectric
effect?  Could any of you provide links to web pages that show how this 
is calculated in as simple a manner as possible?
